I have a friend who had some dental work done and the dentist gave him 800 mg motrin for pain I believe that he has become addicted to them because he has become some one who I don't know now he was the kindest man I have ever known now he is like night and day and this only started after he started taking motrin now he is always needing to take them because he say all the time something is huring. Do you think he is addicted to mortin
